APPN/Boundary Function for DLSw addresses IP Convergence -- The DLSw/APPN boundary function allows users to traverse an IP network while still having access to enterprise-level applications via an APPN/HPR backbone network.
IP Multicast with DLSw Reduces Network Traffic -- As large companies are migrating to an "any-to-any" peer configuration using DLSw, IP Multicast with DLSw improves performance while eliminating overhead.
DLSw provides a reliable method for transporting SNA and NetBIOS traffic across an IP network.
Bay Networks also has extended its DLSw functionality to support PU Type 1 (PU1) devices which are SDLC-attached controllers such as IBM 5294 and 5394 devices.
Bandwidth management within DLSw
allows users to give precedence to network traffic based on the requirements of their business, thereby ensuring fast response times for SNA applications even when using a multiprotocol network.
The Multiprotocol Services package includes all of the above plus support for IPX, AppleTalk 2, VINES, DECnet V, OSI and BGP-4, while the Universal Bridge/SNA Services package adds support for DLSw
Access for Windows' Desktop DLSw supports both versions of the industry-standard DLSw specification, RFC 1795 and RFC 1434, making it highly interoperable.
With Desktop DLSw, Access for Windows is the only PC-to-host connectivity solution to include SNA over TCP/IP connectivity as a standard option," says Maks Wulkan, Eicon Technology's executive vice-president.
As the first industry benchmark to examine SDLC encapsulation using DLSw
on IP backbones, The Tolly Group test measured the throughput and response time characteristics of a single vendor SDLC integration with LAN/WAN internetworks.
Enhancements include Advanced Peer-to-Peer Networking (APPN) support for direct transport over Asynchronous Transfer Mode (ATM), Switched Multimegabit Data Service (SMDS) and Integrated Services Digital Network (ISDN); Data Link Switching Plus (DLSw
+) enhancements, including SNA dial-on-demand routing (DDR) and DLSw
Lite; and Boundary Access Node (BAN) capability.
0, 3Com's DLSw
implementation (RFC 1795) delivers a robust, flexible prioritization mechanism which allows network administrators to allocate the percentage of bandwidth which various users will be allowed.
OpenROUTE also includes Proteon's Bandwidth Reservation, MOSPF and award winning DLSw
implementation (named Data Communications Magazine's "Hot Product of the Year" in January 1995) to improve the performance and reliability of standards-based internetworks.
